Help slowly I despair. My fatter stinks and smokes

Good evening, I’m new here and a proud phaeton owner but slowly I disintegrate. To the vehicle. Phaeton Bj. 12.05, 3.0 diesel bmk engine, with 168000km. It started about 6 months ago he smoked white blue and smelled of diesel in the interior, exchanged all injectors, return line about 2 months ago. A month later Lambdasonde ban 1 and Dpf emergency regenerated because the overloaded was after it was quiet. Now he starts again, in the interior it stinks of exhaust gases when I stand at the traffic light and it smokes again. (Water loss I have no and no oil reproduction). Can someone help me further.
